I INV EN OR I ATTORN EYS.

To all whom 2'25 may concern:

it known. that n 4 W a sub set or th siding-at Folyolae i 1 M den and tto of Massa States of America have new and useful linproven 1' +1 n111011 the owin This invention rel alves and, more part1 I so-calledpuppet tyne w rich n ror use as check val ycct i Y .c 1.

use a valve, or ththe casiig is man connected for con part carrying the1 guides, and the other Another object or A Q vlde in a valve of thetwo? CSLSILO t oe 3 i 1 1 z; ll as described, a spring-pressed valvwhich a is so constructed and mounted that it aut 1- inatically alinesaccurately with its seat even though the two casing :nenl ers may beslightly out of alinernent.

A. further object of the invention is to provide a valve of generallyimproved con struction.

Uther objects and advantages will a one in the following description and1 trative embodiment of the invention in accompanying drawings, inwhich- Figure 1 is an exterior elevational view oi the valve;

Fig. 2 is a sectional elevational view thereof; and

3 is a sectional plan view taken on the line 3-3 of 2.

Referring to these drawings; the valve casing comprises two narts 5 and6, which are reniovably secured together in axial ahnement, as by thescrew thread connection 1. Each casing part 18 of mm l H f t a stand ardpine coupling and thus oc "nlnnnuin mace and presents a reduced p0 anopening vi selling more clo as its opening in b y a v jnw LO bliv ccuccopoi 101i age nst shoulder 18 between the washer and "1g 20 thus acts to'ly force t 1e valve against its seat when the casings 5 and 6 are takenapart, he movement of the valve 15 under the iorce of spring is limitedby the engagement oi the washer 19 with bridge 13,

ereby the valve is not allowed to shoot out of its guides,

.L rably slabbed 013?, as socl'et of a wrench or hereby the valve 15 Ve; b 5 may rec dil be ground to its seat 12', when desired.

The loose connection of the valve stem 16 and the integral reduc dportion 17 with their respective 'des permit the axis of the a to tilts-ightl from the aXis of the ve seat. lhis is considadvaitageous in avalve using is made in two i e co'inectec, with one another 3 ends. Byreason of such it so connection the axis oi one casing may not alineei'actly with that 1 the other and neld in the guides on one easiig,will not aline with. the seat in "he other casing. he described constrretion allows a limited varation in alinement of the axis or the valveand the casing 6, in which it is mounted, and allows the valve to findits OWE alineinent with and closely fit its seat.

The two-piece easing construction, with the seat on one and the valveparts on the other, is important inasmuch as the valve 11.12 y bereadily taken apart and conveniently cleaned, when desired.

The invention has. seen disclosed herein, in an mbodii'nent at presentpreferred, for illustrative purposes, but the scope of the invention is(Lleiined by the appended claims father than by the foregoingdescription.

llxaat I claim is j... A valve, comprising, two easing menu hers renovahly secured together in axial alinement, a valve s at provided in.one of said n'ienibers, valve stem guides all pro-- vided i member, at1) e said seat and having its Ste 11 anouuted in saie guides, and meansto yieldingly hold the valve to its seat.

A valve, eoniprising a easing made up of two members only, such membersbeing substantially cylindrical and being screwed together in axialalineinent, a valve seat provided in one oi in members, a plurality ofvalve stem guides all provided in the other member, a valve to said seatand having its stein HIOUTU'LGC in said guides, and means to yieldinglyhold the valve to its seat.

3. 2r 'alve, comprising, two easing members reinovahly secured togetherin axial a-linenient, a valve seat provided in one of said members, atleast two valve stem guides both provided the other member, a valve toengage saidseat and having its. stein so mounted in said fd" at to tiltto a limited eaxis of the nienih and means to yieldingt; its seat.

a, A valve, comprising,

having a valve seat and two transverse bridges arranged in a ally spacedrelation therein, a valve slidahly mounted in said bridg and having ashoulder intermediate its enos and intermediate said hrioe'es, a washerloosely fitting said stern, and a spring acting etween one or saidbridges and said Washer to yieldingly hold the valve to its seat, saidWElSllGl' being of sufficient diameter to engage the other bridge andlimit the movement of the valve.
